Synchronous-Add Taper/Draft to Cylinder?

For the Synchronous Experts out there, I'm wondering how to use the Steering Wheel to add a taper to a cylinder that I modeled. Short story, I modeled the cylinder and then later realized I need to have a 2deg draft on it. The 3.75 dia should be at the base of the radius on the shoulder side. The end diameter should be smaller.

I could add a Draft feature in Synchronous, or change to Ordered and do the same thing. But, I really want to know if there is a way to do it with the Steering Wheel.

Nope, you aren't missing anything. Can't use Live Section either. A Cylinder is one of those geometric forms that are maintained no matter what during Synchronous edits, so you have to basically change it to a cone with something else (Draft, Revolved Cutout) and then use the Steering Wheel to edit.

@KennyG Ken, you are right. I was pretty certain you could use the live section to make the change. Sounds like a simple enough change.

Then when you think about what synchronous technology is supposed to do it, makes sense. ST won't create geomery and it won't change the face type. In this case we would be moving from a cylinder to cone. That would be like attempting to change a planar face to toridal face.

That cold make for an interesting case for the Catchbook sketching. In there you can double click a line segment and turn it into an arc- with three control points. Likewise, you can turn an arc into a line. Pulling that type of functionality into the live sketch logic would be pretty sweet.

I think they need two rule sets. One for the Steering Wheel face selected, and then another for all the reactive faces. That way you can do things to change the face you have selected to another type but the reactive faces will not change type.

I think a lot of Synch development is based on what the "logical person" would attempt to do. I would think it logical to want to change a cylinder to a cone, especially with Live Section...

The ID changes with a revolved cutout but not when a Draft is applied to the the face meaning the face is replaced in the revolved cutout operation but not in the Draft command, leading me to think that it should be possible to implement in Sync in a way similar to that illustrated by @Imics.

Only development knows some inherent problems with such changes, perhaps just lack of an ER
